I've been pretty much playing since launch, with some breaks along the way. I take longer to get my toons to 50 and to the end of the story, so maybe that's why.

I gotta say, though, I do think that they should've shortened the campaign of each class, in favor of a more extensive endgame. More isn't always better and that's one of the things that irks me about the TOR campaign. They could've done without pretty much half of the content on each planet, in my opinion, which would've been time and resources better spent at working on refining the story experience and on more endgame content.
